In the past, the most commonly used thin-film capacitors were CBB22 capacitor and CL21 capacitor. Among them, CL21 capacitor was largely replaced by CBB22 capacitor, and the frequency of CL21 capacitor was less and less. However, now there is a CL21X capacitor, which has become particularly large. What is CL21X capacitor? What are its characteristics and functions?

CL21X subminiature polyester film capacitor

The full name of CL21x capacitor is metallized polyester film subminiature capacitor. We know that the biggest advantage of CL capacitor compared with CBB capacitor is smaller volume and higher temperature resistance. Therefore, polyester film is often selected when making subminiature capacitor, which can make the capacitor volume smaller. This is also one reason why CL21X capacitor has more users.

Structure of CL21X capacitor

Medium: polyester film

Electrode: metal vacuum evaporation layer (aluminum)

Package: flame retardant epoxy resin (UL94 V-0)

Lead: tinned copper-clad steel wire (CP wire) or tinned copper wire

Characteristics and functions of CL21X capacitor

The volume of CL21X capacitor is very small and has good self-healing; Good appearance consistency; High reliability.
It is mostly used in DC and low pulse occasions. Such as low-frequency filtering, DC isolation, bypass and coupling, etc.
